v In Canada October 6, 1938 ticular advantage where other means of powerare not available and also to permit a user to shave in. the customary place by a wash basin which in some cases may not have any convenience for other mechanical shavers.

A further object is to provide a fluid motor for a dry shaver to be actuated by water power having means to deliver water under pressure from a wash basin faucet in a confined conduit to increase the velocity of the flow and to provide means for the water to return to the wash basin. Another object of the invention is to devise a fluid motor for a dry shaver to be actuated by water power from a wash basin faucet under stand- 20 ard pressure from a city -or other water supply and to provide a device having fewer working parts than devices for'the same purpose now on the market, consequently reducing maintenance expenses and-the primary cost of manufacture. 2 With these and other objects in view that may appear while the description proceeds the invention consists in the novel construction and arrangement of parts as hereinafter more specifically set'forth, claimed and shown in the accom- $0 panying drawing and in which:

Fig. 1 is a general view showing the manner of attaching the fluid motor to the source of power. 1

Fig. 2 is a partial section of the fluid motor.

35 Fig. 3 is a sectional view at right angles to that in Fig. 2.

Fig. 4 is a detail view of the shaver cutter reciprocating means.

-Fig. 5 is a sectional view through the cutter 40 head.

Referring more in detail to the drawing in which similar reference charactersdesignate corresponding parts throughout the several views it will be seen the invention consists of a casing 45 ll having a turbine casing ll mounted therein, said turbine casing is equipped with a water tight hose connection l2 which forms the waste or discharge line I2 and an inlet conduit 13 of greatly reduced dimensions; A turbine rotor 14 Wis mounted concentrically in the inner rounded end I! of the casing fixed on a transverse shaft ii. The conduit I3 is arranged to direct a stream of water at a tangent to the blades ll of the turbine rotor and the casing is reduced in 65 width adjacent to the turbine to restrict the passage of water other than through the blades 01 the turbine rotor.- p

An eccentric collar i8 is mounted on the shaft IS in fixed relation thereto and a rocker arm l9 supported on a pivot 20 and having a semi-cir- 5 cular end 2i engages the said collar. Said rocker has an outwardly extending finger 22 which engages the reciprocal element 23 in the cutter head. Said member is equipped with cutting teeth and arranged to work in conjunction with corresponding teeth of the stationary element 24 of the said cutter head. By this means the ro tary motionof the turbine is converted to a reciprocal movement for the cutter element. 7

Spring means are provided to urge the cutter element into engagement with the stationary element. This consists of a flat spring 25 bearingv centrally on the shaft support and bent at each end to receive pins 28 which are connected to the cutter element. As the spring isflexible 20 the reciprocal movement of the cutter is not interfered with but is kept moving parallel and in engagement with the stationary element. The pins 26 are positioned in longitudinal slots 21 to allow movement thereof and adjustment means in the form of threadable elements 28 are mounted thereon and arranged to bear against the spring so that a. downward movement thereof will increase the spring tension and cause the cutter element to bear stronger against the stationary head. v From the foregoing it will be seen the device as shown constitutes new fluid motor for the operation of a shaver. The water pressure being directed to actuate a turbine rotor by concentration of the flow on the blades thereof and provision being made for the waste or discharge whereby the same is returned to the wash basin waste pipe.

It is believed that the construction and advantages of the structure shown may be apparent from the foregoing paragraphs taken vin con-. junction with the accompanying drawing with-. out further detailed description.

. While the preferred embodiment of the inven-v tion has been disclosed it is understood that. minor changes in the details of construction, combination and arrangement of co- -operating parts may be resorted to within the scopev of what is claimed without departing from the spir- 0 it of the invention.

We claim:

A fluid motor of the type described comprising a flatr'ounded casing having an outlet opening from which extends a tubularoutlet conduit, I5

and opening into the casing at a point substan tiallyopposite to the outlet openinzot the casing whereby the fluid is discharged from the in-- let conduit at a tangent against the blades of said rotor. a flexible hose extending from the said outlet conduit, and a flexible hose extendin; from said inlet conduit. said last mentionedhose being disposed within said first mentioned hose and connected to a source of fluid under pressure. p
